"ran STATES PA'IEN COMBINED PACKER AND HARROW ATTACHMENT FOBSULKY-PLOWS.

To all whom it may concern:

Be it known that I, MARKLE, a subject of the King of Great Britain,residing at Gros Ventre, in the Province of Alberta, Canada, haveinvented certain new and useful Improvements in Combined Packers andHarrow Attachments for Sulky-Plows, of which the following is aspecification.

My invention relates to improvements in combined packer and harrowattachments for sulky plows, and the principal object of my invention isto produce a simple, cheap, but effective implement which can be used inconnection with sulky plows of any make, for the purpose of packing thesubsurface of the soil and covering it over immediately after the furrowis turned, in order to retain the moisture in the ground as long aspossible.

Another ob'ect of my invention is to construct my implement so that itmay be readily attached to, or detached from, any make of sulky plow,and the preferred construction of my invention will be hereinafterparticularly explained, and the parts I claim as new will be set forthin the claims forming part of this specification.

Figure 1 is a side elevation of my implement showing the same attachedto a sulky plow part of which is shown in perspeetive. Fig. 2 is a frontperspective view of my implement, and Fig. 3 is a side elevation of thesame, on an enlarged scale. Figs. 4 and 5 are enlarged details showingthe construction used in attaching my implement to a sulky plow.

In the drawings, like characters of reference indicate correspondingparts in each figure.

In dry soils, particularly the soil in the North Vest Provinces, thesub-surface should be properly packed and the packed sub-surface lightlycovered over as soon as possible after the furrow has been turned, so asto retain the moisture in the ground as long as possible. Now to performthis function of packing the sub-surface of the soil, and lightly coverthe packed subsurface, I have designed my implement, and my preferredconstruction thereof comprises a main frame A in the ends of which ismounted any suitable axle B. Also carried by the axle B is a yoke Cwhich is suitably secured to the lower reach D, the front end F ofREUBEN REED Specification of Letters Patent.

which is bent so as to extend upward through the sleeve E.

G is an upper reach carried by the end F of the lower reach D, and itwill be seen upon referring to Fig. 3 that the reaches I) and G arecarried by the main frame A after any suitable construction. Anysuitable means may be employed for connecting the yoke G with the lowerreach D, as for instance, the strap H.

I are end brackets carried by the main frame A, and mounted in the lowerends of the said brackets is the rock-bar J. Any suitable means may beused for mounting this rock-bar in place, as for instance, nuts andbolts K.

L are a plurality of spring-teeth carried by the rock-bar J, and in astaggered position, if desired. I do not claim any particular meansformounting the teeth L in the rock-bar J, as I may use any suitableconstruction for this purpose. It will of course be understood that thesaid teeth must be mounted in the said rock-bar so that a broken ordamaged tooth may be readily removed and replaced. The teeth L aresimilar to those used on sulky-rakes.

M is a lever suitably secured to the rockbar J.

N a plate connected by any suitable coupling 0 to the upper reach G.

By means of the lever M, the teeth L can be raised or lowered, as willbe understood, and by means of the bolt or pin P passlng throu 'h thelever M and through one of the holes in the plate N, the lever M will beheld in its adjusted position. Of course various means may be used foradjusting the pos1 tion of the teeth L.

In Fig. 1 I show in perspective part of a sulky-plow 2. My attachmentmay be attached to any make of sulky-plow by any suitable means, but mypreferred construction for that purpose consists of two lower reach rods3 and 4: which are carried by the end F of the lower reach D. 20 is abolt held in the member 6 of the frame of the sulky plow, and on thisbolt is placed the Patented llllar. ll, 191m.

eye-provided ends of the reaches 4 and 7 (see Fig. 4:). 21 is a nutscrewing on the bolt 20 to keep these ends of the said reaches in place.Through the outer eye-provided end of the reach-rod 3 passes a bolt 22carried by the member 5 of the frame of the sulky plow. 23 is a nut onthe bolt 22, and

the same is held by the spring 24 upon the reach-rod 3. 25 is a nut onthe bolt 22 hold ing the spring 24 under tension. I of course claimnothing new in these parts. 7 and 8 are upper reach rods which arecarried by the end F of the lower reach D between the top of the sleeveE and the upper reach G. The reach rod 8 is preferably secured to thereach rod 3. 9 is a nut screwing on the top of the end F of the lowerreach D and by means of which the various reaches are held in place.Mounted on the axle B are a plurality of packer wheels 10. As thesulky-plow is advanced the plowshare and mold-board ll of course turnover the soil, and as the packer wheels 10 pass over the earth justturned up by the plowshare and mold-board, the sub-surface of the soilis packed and this packed sub-surface is covered over with a lightcovering of earth by means'of the teeth L.

It will be noticed from the drawings, particularly Fig. 2, that thepacker wheels 10 are provided with substantially V-shaped treads orperipheries. Now by means of this shape of the packer-wheels or theequivalent shape, the wheels pass through the top surface of the -soilwithout packing it, and only pack the sub-surface.

Any make of packer wheels may be used, but I prefer to use the shape ofwheels shown.

Although my attachment is primarily designed for use in connection withgangploys of any make, still it must be understood that I do not confinemyself to using my attachment with this class of plow.

The end F of the lower reach D, and the sleeve E form what I term thehead of the frame for my attachment.

While 1 have described what consider to be the best embodiment of myinvention, I desire it to be understood that the principles can beembodied in different forms, and I desire not to be limited beyond therequirements of the prior art, and the terms of my claims.

What I claim as my invention is:

1. The combination with an implement for plowing land, of an implementof the class described comprising a frame; an axle mounted in saidframe; a plurality of packer-wheels mounted on said axle. and providedwith peripheries substantially V- shaped; a plurality of teethpositioned be hind said paeker-wheels; means whereby said teeth areattached to said frame and adjusted, and means whereby said frame isattached to said plowing implement.

2. An implement of the class described comprising a main frame; an axlemounted in said frame; a plurality of packer-wheels mounted on saidaxle; a lower reach carried by said main frame, and having its front endbent upward; an upper reach carried by said main frame and having itsfree end carried by the turned end of said lower reach; a yoke mountedon said axle and secured to said lower reach; brackets carried by saidframe; a rock-bar mounted in said brackets behind said packer-wheels; aplurality of teeth carried by said rock-bar, and means whereby saidrock-bar is moved so as to adjust said teeth.

In testimony whereof I have afiixed m v signature in presence of twowitnesses.
